Specification of Letters Patent.

Application filed (Jctober 22, 1910. Serial No. 588,468.

To all whom it may concern:

Be it known that I, l lnwaun Ziniu'rnnmn, a citizen of the UnitedStates, residing at Kansas City, in the county of Jackson and State of hlissouri, have invented new and useful Improvements in Reversible Colic-Pots. of which the it'ollowing is a specification.

This invention relates to improvements in apparatus for making cottee,and the object of the invention is to provide a device whereby co'fl'eemay be made of any desired strength without losing any of its aroma, andcomprises a pair of detachable members between which is positioned a 1'ierl:'orated container adapted to receive the ground or pulverizedcofl'ee, the device being reversible so that the cotl'ee can circulatethrough the container from one compartment to the other.

With the above, and other objects in view, which will appear as thedescription. progresses, the invention resides in the novel constructionand combination oil? parts hereina't'ter fully described and claimed.

In the accol'npanying drawings, l igure 1 is a side elevation of thedevice. Fig. 2 is a vertical transverse sectional view of the deviceconstructed in accordance with the present invention. Fig. 3 is asimilar view taken at right angles to Fig. 1.

In the accompanying drawings the numeral 1 designates the ii'nprovedcofl'ee male ing apparatus. This appa -atus 1 comprises essentially apair of sections or vessels 2 and 3. The vessel 3 is adapted to have itsopen mouth inserted within the open mouth of the vessel 2. The apparatusis adapted to be reversible so that either of the vessels may bepositioned upon a flame such as is provided by an ordinary alcohol lampand whereby the coffee may be brewed upon the table where it is adaptedto be served. The bodies of the members 2 and 3 are substantiallysimilar and the description referring to one may be understood asreferring to the second. Each of the vessels 2 and 3 has its closed endprovided with a rim 1: and the bottom of each of the said vessels isflared from its center and terminates at a point adjacent the top of therim t. By constructing the bottom 5 in this manner it will be noted thatthe flame from the lamp is directed to the center of the said bottom andat the same time the col'i'ee percolated "from the container,hereinafter to be described and may have tree passage through an outletfaucet ti which is positioned upon one side of the vessel adjacent thelowm' portion thereof. .llach oi the vessels and It has what may betermed its body portion coneshaped as clearly illustrated in the severalfigures of the drawing and projecting .l'rom sa'id mine-shaped portionis a reduced onnular extension 7. The extension 7 ol' the vessel 23 isof a slightly lesser diameter than that of the vessel 2 so that the saidextension may snugly lit within the extension oi the said vessel .2. Thevessel 3 is provided at the juncture of the annular flange or extension7 and the cone-shaped body 8 with a flanged ring 5). This ring 9 isadapted to receive a washer l0 constructed of corlt or other suitablesubstance which will not allcct the taste oi the coflee and which at thesame time forms a secure bearing for the end oi the flange T of themember I) to prevent the escape oi the aroma from the coll'cc or theleakage oi the brewed coll'ee when the vessels are reversed or upset.The annular flange 7 of the vessel 3 is provided with an annular band11, and positioned between the flanged ring 9 and the band 11 is acoil'ee container 12. This container 12 comprises an annular bodyportion 13 having both its top and its bottom perforated as at l-et.Either the top or the bottom oil the container 12 is removably connectedwith the body 13, so that; access to the interior ol the container maybe obtained when it is desired to till the container with coll'ec, or toremove the grounds therel'rom after the substance of the said coll'eehas been extracted.

llingedly comuicted to the opposite sides of the body S of the vessel 2is a pair oil? arms 1,?) and Ill, both o'l, which are provided with areduced extension 17 terminating in a ball-shaped head 18. This head 18is preferably removably connected with the reduced extension 17 andpositioned between the said head and the shoulder provided by theportion 17 is a turn buckle 19. The body 8 of. the vessel 2 is 'l urtherprovided upon ach ol? its sides with a pair of outwardly extending arms20, the latter being adapted to engage the hinged members 1:") and 16 soas to prevent lateral movement of the same when the device is in theposition illustrated in the figures of the drawing. The upper portion ofthe turn buckle 19 ad- 'jacent its connection with the head 18 isthreaded and the said threads are adapted to co-act with the malethreads 21 provided upon a rod 22. The rod 22 has its free end providedwith an off-set head 23 and the body of the vessel 3 is formed withspaced lugs 24 between which the head of the rod 22 is adapted to rest.By this arrangement,

it will be noted that the turn buckle 19 will effectively and securelyconnect the members 2 and 3 together and force the edges of the flange 7of the member 3 tightly into contact with the washer 10 provided uponthe flanged ring 9 of the vessel 2.

In order to provide for the handling of the coii'e pot without danger ofinjury to the hands of the operator, the flanged extension 7 of thevessel 2 is provided with suitable handles 25. These handles 25 arearranged diametrically opposite and at substantially right angles to theturn buckles or securing members for the vessels. The handles 25 areformed with longitudinally extending arms 26, whereby the handles properare positioned a distance away from the vessels.

It will be noted that the uppermost offset of the pot is to have itsvalve open so that the same may be employed as an air and steam vent.The extending arms 20 are preferably closed across their ends to formwhat may be termed a staple which is adapted to prevent the hingedmembers 15 and 16 from dropping down when the pot is opened.

Having thus fully described the invention, what I claim as new is In areversible coffee pot, the combination including a pair of vessels, eachof said vessels having a conical body and a reduced annular extension,one of said extensions adapted to be fitted snugly Within the other ofsaid annular extensions, annular flanges being formed on the innersurface of said extensions and adjacent the inner ends thereof, one ofsaid flanges being substantially L-shaped whereby to form an annulargroove for the reception of the adjacent edge of the inner extension, acontainer adapted to be received between the flanges, and means forremovably connecting the vessels together, said means comprising rods,turn buckles for connecting the rods, each of the said vessels beingprovided with ears, said ears being adapted for the reception of theouter ends of the rods.

In testimony whereof I affix my signature in presence of two witnesses.
